Weather in Iceland in August

Driving conditions in Iceland during the summer months are at their prime, and there’s no concerns of snow, or road closures meaning that all of Iceland will be accessible for visiting. Weather conditions are also at their most favourable, making the summer a very popular time for tourists to visit Iceland.

Average temperature

During August, the average temperature is normally 10.5°C or 51°F, allowing for warmer summer clothes to still be in play, especially in Northern and Eastern Iceland. High temperatures in August usually hit 13°C or 55°F, with the lows getting only slightly cooler at 8°C or 46°F.

August is the last final month before things start to cool off, and slowly make their ways down towards the freezing point that becomes a reality in the late fall and winter months.

What to Pack & Wear in August

You can certainly pack much lighter in August than you would during a winter trip to Iceland, but you still want to ensure you have the right items for your trip.

You’ll still want to pack a light coat for your visit, and you’ll definitely want to be well-equipped with some rain and windproof gear. Both fleece and wool are still great items to have handy in August, and a pair of gloves will also be advisable for the late nights after the sun sets and temperatures tend to cool down a bit.

For all times of year in Iceland, if you're planning to get out and explore, you'll want to have a sturdy pair of hiking boots at the ready. Normal shoes do great for city activities, so you should have both on hand to easily make the switch when the time is right.

Driving in August

Driving in Iceland in summer is a much easier task than during any of the other times of year. You won’t need to worry about road closures, or difficult driving conditions that are normally present on the island. Normally, in the highlands, you’ll still need a 4x4 vehicle for more difficult passings as you may encounter fording rivers. If so, ensure that you follow directions on how to approach such situations, and never venture into dangerous situations involving water if you’re unsure.

Nonetheless, you should always remember that driving in Iceland is probably a bit different than back home. Remember - off-road driving is not only frowned upon, but is illegal in Iceland. Only drive on clearly marked roads, in order not to sustain damage to your vehicle, or even a large fine.

Also remember not to stop off the side of the road, and only in designated areas where parking is allowed. When you stop off the side of the road, you put not only yourself, but others at risk of life-threatening injuries.

Iceland’s Volcanic Trails

Exploring the wilderness during the summer months is one of the best times to get off the beaten path, and undertake a unique experience during your time in Iceland. Visiting Iceland's volcanic trails is certainly one of those unique experiences, where you'll have the chance to visit a remote hiking trail that weaves through one of Iceland's most stunning volcanic regions.

Your hike will begin up to the top of the Sveinstindur mountain, with spectacular views over the long lake, known better as Langisjór. Along the way, you'll find moss-covered formations, waterfalls, canyons and craters left over from one of the greatest eruptions of all time. Get an up close look at the black sands and green moss found in the Mælifellssandur desert as you hike through this impressive landscape. In the evenings, you'll have the chance to relax with your group and local guide in cozy mountain huts that are located along the volcanic trail.

Iceland Southern Coast Self-Drive Tours

Self-drive tours are an excellent way to get out, hit the open road and have a flexible, yet guided itinerary where you’ll have full control over what you do and see.

You'll definitely want to visit the gems of Iceland's south, including the many waterfalls, geysers and black sandy beaches that many come to visit.
